When the mobile terminal reads the two-dimensional bar code including the SSID of the access point, the network to be connected is switched. If the mobile terminal is already connected to a network that can communicate with the communication device, the mobile terminal reads the two-dimensional bar code including the SSID of the access point, which causes unnecessary network switching. When unnecessary network switching occurs, the user may be required to enter the authentication information for connecting to the network again, which may increase the time and effort of the user. In other words, for a user who knows that the mobile terminal is already connected to the network that can communicate with the communication device, the SSID of the access point is not necessarily included in the two-dimensional bar code displayed by the communication device. No need.

So as one aspect of the present invention, in a communication device, and one object thereof is to provide a proper user a two-dimensional bar code including the SSID of the access point function of the communication device.

The communication device as one aspect of the present invention is a communication device having an access point function for operating the communication device as an access point for executing wireless communication with an external device, and can be operated by a user having administrator authority. Based on this, the setting means for setting whether to allow or prohibit the use of the access point function as the operation setting of the communication device and the setting means for permitting the use of the access point function as the operation setting are set. SSID (Service Set Id) that identifies the access point according to the reception of a user operation for displaying a screen related to execution of wireless communication with an external device when the communication device is operated as the access point. The access point function is controlled to display a first two-dimensional bar code including information indicating the SSID set based on the user operation as the setting of the access point function, and the access point function is set as the operation setting. When prohibition of use is set by the setting means, a display control means for controlling not to display the first two-dimensional bar code even when a user operation for displaying the screen is accepted. It is characterized by having.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. It should be noted that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential for the means for solving the invention.

(Embodiment 1)
First, the configuration of the printing system according to the present embodiment will be described with reference to FIG. The printing device 100 is connected to the network 140 and can communicate with an external device such as a PC 130 or a mobile terminal 110 via the network 140. The PC 130 transmits print data to the printing apparatus 100 via the network 140. The mobile terminal 110 transmits print data to the printing device 100 via the access point 120. The printing apparatus 100 that has received the print data executes a printing process based on the received print data.

Further, the printing device 100 can operate in the access point mode. When the printing device 100 operates in the access point mode, the printing device 100 generates an SSID (Service Set Identifier) and acts as an access point. By connecting the mobile terminal 110 to the SSID generated by the printing device 100, it is possible to establish direct wireless communication between the printing device 100 and the mobile terminal 110 without going through a relay device such as an access point 120. ..

Next, the configuration of the printing apparatus 100 will be described with reference to FIG. Although the printing device 100 of the present embodiment is assumed to be a multifunction device, it may be a printer that does not have a scanner function.

The CPU 201 reads out the control program stored in the ROM 202 and executes various processes for controlling the operation of the printing device 100. The CPU 201 is connected to another unit by a bus 200. The ROM 202 stores the control program. The RAM 203 is used as a temporary storage area for the main memory, work area, etc. of the CPU 201. The HDD 204 is a non-volatile storage medium for storing various data such as print data and scanned images.

In the case of the printing apparatus 100, one CPU 201 shall execute each process shown in the flowchart described later, but other embodiments may be used. For example, a plurality of CPUs may cooperate to execute each process shown in the flowchart described later. Further, a part of the processing shown in the flowchart may be executed by using a hardware circuit.

The wireless communication unit 205 has a wireless LAN function and executes wireless communication with the access point 120. Further, the wireless communication unit 205 can operate in the access point mode. When the wireless communication unit 205 operates in the access point mode, the wireless communication unit 205 behaves as an access point, so that direct wireless communication can be established between the mobile terminal 110 and the printing device 100.

The printer 206 executes a printing process on a sheet based on print data received from an external device, a scanned image generated by the scanner 207, and the like. The scanner 207 scans the document and generates a scanned image. The scanned image generated by the scanner 207 is printed by the printer 206 or stored in the HDD 204.

The operation unit 208 includes a liquid crystal display unit having a touch panel function and a keyboard, and displays various operation screens. The user can input instructions and information to the printing device 100 via the operation unit 208.

The network I / F 209 connects to the network 140 by a LAN cable and executes communication with an external device (for example, PC 130) on the network. The network I / F 209 receives the print data transmitted from the external device, and the print process based on the print data received by the printer 206 is executed.

The printing device 100 is given as an example of a communication device that can operate in the access point mode. The communication device to which the present invention can be applied is not limited to the printing device 100. The present invention can be applied to various electronic devices such as digital cameras, video cameras, smartphones, and tablet PCs as long as they can operate in the access point mode.

When connecting the mobile terminal 110 to the printing device 100 operating in the access point mode, the user inputs the SSID of the printing device 100 to the mobile terminal 110 or selects the SSID of the printing device 100 from the list of search results of the access point. There is a need to. In order to eliminate this trouble, the printing apparatus 100 displays a two-dimensional bar code including the SSID of the printing apparatus 100. Further, the printing device 100 can also display a two-dimensional bar code that does not include the SSID according to the instruction of the user. That is, the printing apparatus 100 of the present embodiment is characterized in that it switches between displaying a two-dimensional bar code including the SSID and displaying a two-dimensional bar code not including the SSID according to a user's instruction. do. The display of this two-dimensional bar code will be described in detail below.

First, the screen displayed by the printing apparatus 100 will be described with reference to FIG. The menu screen 300 of FIG. 3A is a screen displayed by the operation unit 208, and is used as an initial screen displayed first when the printing device 100 is started.

The button 301 is a button for using the copy function. When the user selects the button 301, the copy screen is displayed. The button 302 is a button for using the SEND function (a function of transmitting the original image read by the scanner 207 to an external device on the network 140). When the user selects the button 302, the SEND screen is displayed. The button 304 is a button for displaying various setting screens.

The setting screen 310 of FIG. 3B is a setting screen for setting permission / prohibition of the access point mode among a plurality of setting items displayed when the button 304 is selected on the menu screen 300. In FIG. 3B, the access point mode is called a direct connection function.

When a user (for example, a system administrator) selects the button 311 on the setting screen 310, the user (for example, a system administrator) is permitted to operate in the access point mode. If the general user is allowed to use the access point mode, the system administrator may select the button 311. On the other hand, when the user (for example, the system administrator) selects the button 312 on the setting screen 310, the operation in the access point mode is prohibited. If the general user is not allowed to use the access point mode, the system administrator may select the button 312. When the user selects the confirmation button 313, the result of the setting by the setting screen 310 is stored in the HDD 204.

The explanation returns to the explanation of the menu screen 300 of FIG. 3 (A). When the user selects the button 303 on the menu screen 300, the direct connection screen and the infrastructure connection screen described later with reference to FIGS. 4 and 5 are displayed. On the direct connection screen and the infrastructure connection screen, a two-dimensional bar code for connecting the mobile terminal 110 to the printing device 100 is displayed. When the user selects the button 303, which of the direct connection screen and the infrastructure connection screen is initially displayed is switched depending on the result of the setting by the setting screen 310. When the direct connection function is set to "ON", that is, when the use of the access point mode is permitted, the printing device 100 initially displays the direct connection screen. This screen transition will be described with reference to FIG. On the other hand, when the direct connection function is set to "OFF", that is, when the use of the access point mode is prohibited, the printing device 100 initially displays the insuffler connection screen. This screen transition will be described with reference to FIG.

FIG. 4 will be described. When the direct connection function is set to "ON", the printing apparatus 100 displays the direct connection screen 400 of FIG. 4A in response to the selection of the button 303. The reason why the direct connection screen 400 is displayed is that the direct connection function is set to "ON" and it is assumed that the user uses the access point mode.

When the user selects the start button 401 on the direct connection screen 400, the printing device 100 starts the operation of the access point mode. Further, the printing apparatus 100 generates an SSID, a connection key (for example, a WEP key), and an IP address used in the access point mode, and further generates a two-dimensional bar code described later. Then, the printing apparatus 100 displays the direct connection screen 410 of FIG. 4 (B).

411 and 412 of the direct connection screen 410 of FIG. 4B show the SSID and the connection key generated by the printing apparatus 100, respectively. Further, the two-dimensional bar code 413 is displayed on the direct connection screen 410. The two-dimensional bar code 413 is a QR code (registered trademark) and is generated by the printing apparatus 100 based on the SSID and the connection key used in the access point mode. The mobile terminal 110 can recognize the SSID, connection key, and IP address generated by the printing device 100 by reading the two-dimensional bar code 413 using the camera function. Then, the mobile terminal 110 can establish wireless communication with the printing device 100 by connecting to the recognized SSID.

When the user selects the stop button 414 on the direct connection screen 410, the printing device 100 ends the operation of the access point mode. Then, the screen displayed by the printing apparatus 100 transitions from the direct connection screen 410 to the direct connection screen 400.

When the user selects the button 402 on the direct connection screen 400, or when the user selects the button 415 on the direct connection screen 410, the printing device 100 displays the infrastructure connection screen 420 of FIG. 4C. The device name of the printing device 100 and the IP address of the printing device 100 are displayed on 421 and 422 of the infrastructure connection screen 420, respectively.

Further, a two-dimensional bar code 423 is displayed on the infrastructure connection screen 420. The two-dimensional bar code 423 is a QR code (registered trademark) like the two-dimensional bar code 413 of the direct connection screen 410, but the two-dimensional bar code 423 does not include the SSID of the access point. The two-dimensional bar code 423 is generated by the printing device 100 based on the IP address of the printing device 100. The mobile terminal 110 can recognize the IP address of the printing device 100 by reading the two-dimensional bar code 423 using the camera function. Then, the mobile terminal 110 can transmit the print data to the printing device 100 with the recognized IP address as the destination.

When the user selects the button 424 on the infrastructure connection screen 420, the printing device 100 displays the direct connection screen 400 of FIG. 4A or the direct connection screen 410 of FIG. 4B. When the printing device 100 has already started the operation of the access point mode, the printing device 100 displays the direct connection screen 410 of FIG. 4B in response to the user selecting the button 424. On the other hand, when the printing device 100 is not operating in the access point mode, the printing device 100 displays the direct connection screen 400 of FIG. 4A in response to the user selecting the button 424.

When the direct connection function is set to "ON", the user can switch whether to display the two-dimensional bar code 413 or the two-dimensional bar code 423 by using the button 402, the button 415, and the button 424. Can be done. When it is desired to establish wireless communication in the access point mode with the printing device 100, the user may display the two-dimensional bar code 413 for direct connection. On the other hand, when it is desired to make the mobile terminal 110 recognize only the address of the printing device 100 (when it is desired to perform pairing), the user may display the two-dimensional bar code 423 for infrastructure connection.

Next, FIG. 5 will be described. When the direct connection function is set to "OFF", the printing device 100 displays the infrastructure connection screen 500 of FIG. 5A in response to the selection of the button 303. The infrastructure connection screen 500 is displayed because the use of the access point mode is prohibited.

The infrastructure connection screen 500 is the same screen as the infrastructure connection screen 420 of FIG. 4 (C). The device name of the printing device 100 and the IP address of the printing device 100 are displayed on 501 and 502 of the infrastructure connection screen 500, respectively. Further, the two-dimensional bar code 503 is displayed on the infrastructure connection screen 500. The two-dimensional bar code 503 is a QR code (registered trademark) and is generated by the printing device 100 based on the IP address of the printing device 100.

When the user selects the button 504 on the infrastructure connection screen 500, the printing device 100 displays the direct connection screen 510 of FIG. 5 (B). In the case of the direct connection screen 510, the message 511 indicating that the access point mode cannot be used is displayed because the direct connection function is set to "OFF", that is, the use of the access point mode is prohibited. Further, unlike the direct connection screen 400, the start button 401 is not displayed on the direct connection screen 510. When the user selects the button 512 on the direct connection screen 510, the printing device 100 displays the infrastructure connection screen 500 of FIG. 5A.

As described above, when the direct connection function is set to "ON", the printing apparatus 100 displays both the two-dimensional bar code 413 including the SSID and the two-dimensional bar code 423 not including the SSID. Can be done.

Further, the user can select whether to use the two-dimensional bar code 413 including the SSID or the two-dimensional bar code 423 not including the SSID according to his / her purpose of use. For example, if the mobile terminal 110 is not connected to the same network as the printing device 100, it is desirable for the user to use the two-dimensional bar code 413 including the SSID. As a result, it is possible to reduce the trouble of inputting the SSID to the mobile terminal 110 and selecting a desired SSID from the search result of the access point.

On the other hand, when the mobile terminal 110 is already connected to the same network as the printing device 100, it is desirable that the user uses the two-dimensional bar code 423 that does not include the SSID. When the mobile terminal 110 reads the two-dimensional bar code including the SSID, the network to be connected is switched. By using a 2D barcode 423 that does not include the SSID, it is possible to prevent unnecessary network switching from occurring, and to prevent users from being asked to enter authentication information to connect to the network again. can.

Next, a process of generating and displaying a two-dimensional bar code (two-dimensional bar code 423, two-dimensional bar code 503) that does not include the SSID and a two-dimensional bar code (two-dimensional bar code 413) that includes the SSID will be described. .. First, the process related to the generation and display of the two-dimensional bar code not including the SSID will be described with reference to FIGS. 6 and 7.

The flowchart of FIG. 6 is a process executed when the printing apparatus 100 is started. Each step shown in the flowchart of FIG. 6 is processed by the CPU 201 expanding the control program stored in the memory such as the ROM 202 into the RAM 203 and executing the step.

First, in step S601, the CPU 201 generates a two-dimensional bar code for infrastructure connection based on the IP address of the printing device 100. The two-dimensional bar code for infrastructure connection includes the IP address of the printing device 100 but does not include the SSID of the access point, such as the two-dimensional bar code 423 and the two-dimensional bar code 503. Then, in step S602, the CPU 201 stores the two-dimensional bar code for infrastructure connection generated in step S601 in the HDD 204.

As described above, using the flowchart of FIG. 6, the configuration for generating the two-dimensional bar code for infrastructure connection at the timing when the printing apparatus 100 is started has been described. Even when the IP address of the printing device 100 is changed, a new two-dimensional bar code for infrastructure connection is newly generated and stored in the HDD 204.

Next, a configuration for displaying a two-dimensional bar code for infrastructure connection will be described using the flowchart of FIG. 7. Each step shown in the flowchart of FIG. 7 is processed by the CPU 201 expanding the control program stored in the memory such as the ROM 202 into the RAM 203 and executing the step.

In step S701, the CPU 201 determines whether or not the display instruction of the infrastructure connection screen has been received from the user. The infrastructure connection screens of the present embodiment are the infrastructure connection screen 420 of FIG. 4 (C) and the infrastructure connection screen 500 of FIG. 5 (A). When the display instruction of these screens is received from the user, the CPU 201 determines that the display instruction of the infrastructure connection screen has been received from the user, and the process proceeds to step S702. On the other hand, when the display instruction of the infrastructure connection screen 420 or the infrastructure connection screen 500 is not received from the user, the CPU 201 waits until the display instruction of the infrastructure connection screen 420 or the infrastructure connection screen 500 is received from the user.

Next, in step S702, the CPU 201 displays an infrastructure connection screen including a two-dimensional bar code for infrastructure connection (two-dimensional bar code stored in step S602). In the case of the present embodiment, the CPU 201 controls the operation unit 208 so as to display the infrastructure connection screen 420 of FIG. 4 (C) and the infrastructure connection screen 500 of FIG. 5 (A). As a result, the user can have the mobile terminal 110 read the two-dimensional bar code for infrastructure connection.

Next, the process related to the generation and display of the two-dimensional bar code including the SSID will be described with reference to FIG. Each step shown in the flowchart of FIG. 8 is processed by the CPU 201 expanding the control program stored in the memory such as the ROM 202 into the RAM 203 and executing the step.

In step S801, the CPU 201 determines whether or not a display instruction on the direct connection screen has been received from the user. The direct connection screen of the present embodiment is the direct connection screen 400 of FIG. 4B, the direct connection screen 410, and the direct connection screen 510 of FIG. 5B. When the display instruction of these screens is received from the user, the CPU 201 determines that the display instruction of the direct connection screen has been received from the user, and the process proceeds to step S802. On the other hand, when the display instructions of the direct connection screen 400, the direct connection screen 410, and the direct connection screen 510 are not received from the user, the CPU 201 waits until the display instructions of these screens are received from the user.

Next, in step S802, the CPU 201 determines whether or not the setting of the direct connection function is ON. The process of step S802 is executed when the CPU 201 confirms the result of the setting on the setting screen 310 of FIG. 3 (B). When the setting of the direct connection function is ON, that is, when the use of the access point mode is permitted, the process proceeds to step S803. On the other hand, when the setting of the direct connection function is not ON, that is, when the use of the access point mode is prohibited, the process proceeds to step S811.

Next, step S803 will be described. In step S803, the CPU 201 determines whether or not the two-dimensional bar code for direct connection has been generated. The two-dimensional bar code for direct connection includes the IP address of the printing device 100 and the SSID of the access point, as in the two-dimensional bar code 413. If the two-dimensional bar code for direct connection has already been generated, that is, if the two-dimensional bar code for direct connection is stored in the HDD 204, the process proceeds to step S810. On the other hand, if the two-dimensional bar code for direct connection has not been generated, that is, if the two-dimensional bar code for direct connection is not stored in the HDD 204, the process proceeds to step S804.

Next, step S804 will be described. In step S804, the CPU 201 displays a direct connection screen that does not include a two-dimensional bar code for direct connection. In the case of the present embodiment, the CPU 201 controls the operation unit 208 so as to display the direct connection screen 400 of FIG. 4A.

Next, in step S805, the CPU 201 determines whether or not the start button instructing the user to start the operation of the access point mode is pressed. When the user presses the start button 401 on the direct connection screen 400, the process proceeds to step S806. On the other hand, if the user has not pressed the start button 401, the CPU 201 waits until the user presses the start button 401.

Next, in step S806, the CPU 201 starts the operation of the access point mode. Specifically, the CPU 201 controls the wireless communication unit 205 so as to start the operation of the access point mode.

Next, in step S807, the CPU 201 generates an SSID, a connection key, and an IP address to be used in the access point mode. Random values may be generated for this information, or fixed values preset by the user may be used.

Next, in step S808, the CPU 201 generates a two-dimensional bar code for direct connection based on the SSID, connection key, and IP address generated in step S807. The two-dimensional bar code generated here is, for example, the two-dimensional bar code 413 of FIG. 4 (B).

Next, in step S809, the CPU 201 stores the two-dimensional bar code for direct connection generated in step S808 in the HDD 204. When the process shown in the flowchart of FIG. 8 is executed again after the two-dimensional bar code for direct connection is stored in the HDD 204, it is determined in step S803 that the two-dimensional bar code for direct connection has already been generated. become.

The two-dimensional bar code for direct connection stored in step S809 is deleted at a predetermined timing. For example, when the stop button 414 of FIG. 4B is pressed by the user or the operation of the access point mode is stopped due to a timeout, the two-dimensional bar code for direct connection stored in step S809 is deleted.

Next, in step S810, the CPU 201 displays a direct connection screen including a two-dimensional bar code for direct connection (two-dimensional bar code stored in step S809). In the case of the present embodiment, the CPU 201 controls the operation unit 208 so as to display the direct connection screen 410 of FIG. 4 (B). As a result, the user can have the mobile terminal 110 read the two-dimensional bar code for direct connection. Even when it is determined in step S803 that the two-dimensional bar code for direct connection has been generated, the operation unit 208 displays the direct connection screen 410 of FIG. 4B in step 810.

Next, step S811 will be described. If it is determined in step S802 that the setting of the direct connection function is not ON, that is, the use of the access point mode is prohibited, the process proceeds to step S811. Then, in step S811, the CPU 201 displays a message indicating that the direct connection function cannot be used. Specifically, the CPU 201 controls the operation unit 208 so as to display the direct connection screen 510 of FIG. 5 (B). Message 511 is displayed on the direct connection screen 510. This allows the user to know that the direct connection function cannot be used, that is, the use of the access point mode is prohibited.

As described above, according to the present embodiment, the printing apparatus 100 has a two-dimensional bar code including the address and SSID of the printing apparatus 100 and a two-dimensional bar code including the address of the printing apparatus 100 but not including the SSID. Both can be displayed. In the present embodiment, the IP address has been described as an example of the address of the printing device 100, but the MAC address of the printing device 100 may be used, or both the IP address and the MAC address may be used.

Further, for the user, it is possible to switch between the two-dimensional bar code including the SSID and the two-dimensional bar code not including the SSID according to the user's own purpose of use.

(Embodiment 2)
In the first embodiment, the configuration of displaying the two-dimensional bar code including the SSID and the two-dimensional bar code not including the SSID on the operation unit 208 according to the output instruction of the user has been described, but it is output to the user in another form. You may. For example, a two-dimensional bar code including the SSID and a two-dimensional bar code not including the SSID may be printed on the sheet in response to a print instruction from the user to be output to the user.

The sheet 901 of FIG. 9A shows an example in which the printer 206 prints a two-dimensional bar code including the SSID on the sheet. The two-dimensional bar code 902 printed on the sheet 901 includes the SSID, the connection key, and the IP address of the printing device 100 used in the access point mode, like the two-dimensional bar code 413 of FIG. 4 (B).

Further, the sheet 911 of FIG. 9B shows an example in which the printer 206 prints a two-dimensional bar code not including the SSID on the sheet. The two-dimensional bar code 912 printed on the sheet 911 does not include the SSID of the access point, like the two-dimensional bar code 423 of FIG. 4 (C) and the two-dimensional bar code 503 of FIG. 5 (A). Includes the IP address of.

As described above, the user can also have the mobile terminal 110 read the two-dimensional bar code by printing the two-dimensional bar code on the sheet.

You may use it. For example, even if Wi-Fi Direct is used, the mobile terminal 110 and the printing device 100 can directly execute wireless communication. Also in the case of Wi-Fi Direct, the printing device 100 generates an SSID, a connection key, and an IP address.

Further, in each of the above-described embodiments, the QR code (registered trademark) has been described as an example of the two-dimensional bar code, but other types of two-dimensional bar codes may be used.
